leishmania is a protozoan parasite belonging to the family trypanosomatidae, which is found among 88 different countries. the parasite lives as an amastigote in vertebrate macro­phages and as a promastigote in the digestive tract of sand fly. it can be cultured in the laboratory us­ing appropriate culture media. although the sexual cycle of leishmania has not been observed during the promastigo...

The cis- and trans-dichloro- and diiodo-platinum(II) complexes containing two acetonimines (cis- and trans-[PtX(2){HN=C(CH(3))(2)}(2)], 1 and 2 for X = Cl and 1' and 2' for X = I, respectively) or one acetonimine and one ammine (cis- and trans-[PtX(2)(NH(3)){HN=C(CH(3))(2)}], 3 and 4 for X = Cl and 3' and 4' for X = I, respectively) have been prepared from platinum-ammine precursors by condensa...

Permethrin is a widely used pyrethroid insecticide for which the toxicokinetics of exposure biomarkers in humans is not fully documented. The time courses of key biomarkers of permethrin exposure were thus assessed in accessible biological matrices of orally exposed volunteers. Six volunteers ingested 0.1 mg/kg body weight of permethrin (60:40 trans/cis). Blood samples were withdrawn at fixed p...

extended abstract 1. introduction the translation of literary works in iran has always been subject to social and political conditions, intellectual tendencies, and dominant ideologies of the related historical period. hence, in each period the translators were inclined to translate specific literary works according to the beliefs and viewpoint of a distinguished political and social group. thu...

The irradiation of ruthenium-sulfur dioxide complexes of general formula trans-[Ru(II)(NH(3))(4)(SO(2))X]Y with laser light at low temperature results in linkage isomerization of SO(2), starting with eta(1)-planar S-bound to eta(2)-side S,O-bound SO(2). The solid-state photoreaction proceeds with retention of sample crystallinity. Following work on trans-[Ru(NH(3))(4)Cl(eta(1)-SO(2))]Cl and tra...

An isomeric mixture of linoleic acid hydro peroxides, 13-hydroperoxy-cis9 trans-II-octadecadienoic acid (79%) a~d 9-hydroperoxy-eis-12,trans-IO-octadecadienoic acid (21 %), was decomposed homolytically by Fe(I!) in an ethanolwater solution. In one series of experiments, the hydroperoxides were decomposed by catalytic concentrations of Fe (II). The 10.5 M Fe(III) used to initiate the decompositi...

The effect of alkyl substituents on the C-phenyl and/or the N-Phenyl ring of benzophenylhydroxamic acid on their molecular structure and hydrogen bonding has been investigated. The predominant configuration in CHCl3 is determined by steric and electronic effects. Substituents on the C-phenyl ring favor the cis configuration, while substituents in the N-phenyl ring favor a trans c...

This work reports the syntheses, structures and some photochemistry in DMF of the cobalt complexes trans-[Co(2)Cl2]Cl 0.5CH3OH and trans-[Co (3)Cl2]Cl 4H2O, where 2 is 6-(anthracen-9-ylmethyl)-1,4,8,11tetraazacyclotetradecane-5,7-dione and 3 is 6-(anthracen-9-ylmethyl)-1,4,8,11-tetraazacyclotetradecane. In the preparation of the macrocyclic ligand, 3, the formation of a polycyclic bis(aminal) i...
